Key Features
- Measures the force on a current-carrying conductor in a magnetic field
- Printed circuit board coil mounted on a support handle
- Two coils: 5 turns and 10 turns
- Rated at 2 A
- Used with a permanent magnet on a digital balance pan
- Allows force and field strength to be calculated
About This Product
A permanent magnet is placed on the pan of a digital balance and the BIL coil is mounted in a vertical plane between the magnets. When the coil is connected to a low voltage power supply and ammeter, the balance is deflected and the new reading is taken. From this, the force on the current-carrying conductor and the field strength can be calculated.
